I remember a manga from a while ago, but I can't find it anymore. What's!
Question: I thought the title was "AI". It is not video girl AI. The story has to do with the end of the world. people have lost the ability to reproduce. The main character is a guy who is handicapped and is given an "AI" as a companion that he can care for. She can only live for about a year and the end of the world is approaching quickly. PLEASE TELL ME WHAT IT IS!
